A discharge pump equipped with a push-down head in which a nozzle is opened and closed by advancing and retracting a valve rod member by a lever member and a first pressing member, wherein a second pressing member is provided between the base and the tip of the valve rod member to prevent back flow of air. A push-down head discharge pump has a head body configured by providing a liquid flow pipe to the lower surface of a laterally facing cylinder section so as to extend vertically downward from the lower surface, the liquid flow pipe communicating with a stem of a discharge pump, the cylinder section having a nozzle opened at the front thereof. When the head body is pushed down, a valve rod member mounted in the cylinder section is advanced and retracted. The valve rod member is composed of the base and the tip, and a second pressing member is mounted between the base and the tip.
